Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.Specific embodiment mode described herein only for explaining the present invention, the protection domain be not intended to limit the present invention.
The servo-actuated supporting member of hard and soft multiple spot for mirror image processing of the present invention as shown in drawings, it comprises pedestal 1, described pedestal along the circumferential direction has circumference ladder hole 10 that multiple axis is set parallel to each other uniformly, the center ladder hole 12 arranged with circumference ladder hole axis being parallel is had in described pedestal centre position, internal thread is provided with in the left side of described multiple circumference ladder hole and center ladder hole, in each circumference ladder hole, from left to right threaded connector 4 is installed successively, left spring 5 and bar overlap the support bar 7 having right spring 6, described threaded connector 4 is connected with the internal thread 11 of circumference ladder hole, left spring 5 is pressed between the shoulder block of threaded connector 4 and support bar 7, right spring 6 is pressed between the shoulder block of support bar 7 and circumference ladder hole hole shoulder 14, left spring 5 is identical with right spring 6 and be arranged in the shoulder block two ends of support bar 7 symmetrically.Auxiliary Universal caster 2 is connected with at the right-hand member of described support bar 7.The left side end of thread of main supporting rod is connected in the right-hand member of described center ladder hole 12 by nut 8, be connected with main Universal caster 3 at the right-hand member of described main supporting rod.Auxiliary Universal caster 2 and main Universal caster 3 are arranged on outside pedestal right side.
Preferred described pedestal is cylindrical, the external cylindrical surface of pedestal 1 has arc groove 15 to alleviate supporting member weight.The internal thread 11 of circumference ladder hole is connected with threaded connector 4, can, by turn threaded connection 4 to adjust the position of auxiliary Universal caster 2, install and use in process, and the internal thread 13 of center ladder hole is for being connected with support executing agency.
Support bar 7, left spring 5, right spring 6 form flexible support bar 9.The thin axle of described support bar 7 has screw thread for being connected with auxiliary Universal caster 2.Threaded connector 4 can adopt soket head cap screw 4 without a head, can adjust the position of auxiliary Universal caster 2 by rotating soket head cap screw 4 Compress Spring without a head, and soket head cap screw 4 without a head is 2:1 with the Displacement Ratio of auxiliary Universal caster 2.Different flexible support rigidity can be realized by the spring using different-stiffness instead.The spring of support bar 7 two ends parallel connection makes spring supporting rigidity double.
The quantity of the preferred support bar of the present embodiment is six, and the angle intervals between each support bar is 60 °.
Described auxiliary Universal caster 2 and main Universal caster 3 commercially available, such structure decreases frictional force to greatest extent, also can move to all directions easily under heavier load effect.
The course of work of this device is adopted to be:
When adding man-hour to thin-wall part mirror image, soket head cap screw 4 without a head is regulated to make the auxiliary Universal caster 2 of circumferencial direction exceed certain distance than center main Universal caster 3 in advance.The auxiliary Universal caster 2 of thin-wall part compression circumferencial direction is until thin-wall part touches center main Universal caster 3.Auxiliary Universal caster 2 pairs of thin-wall parts carry out flexible support, and main Universal caster 3 pairs of thin-wall parts carry out rigid support.The cutter that supporting member follows thin-wall part opposite side organisation of working moves with identical speed and direction.The existing flexible support of the present invention reduces the flutter of thin-wall part, also has rigid support accurately to locate thin-wall part.Multi-point support increases Area of bearing simultaneously, reduces control difficulty.
It should be noted that; although be described in detail the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited only to above-mentioned detailed description of the invention; above-mentioned embodiment is only schematic; be not restrictive, the person skilled of this area is subject to enlightenment of the present invention, when not departing from present inventive concept and claims; can also make a lot of form, these all belong to protection scope of the present invention.
